Shrinking the Ozone Hole

           In 2012 the Antarctic Ozone Hole was reported by NASA to be the second smallest size it has been in 20 years.  It had reached it largest size on record Sept. of 2000 at 11.5 million square miles.  It also recorded a minimum value of total ozone that year recorded as the second highest overall level in two decades.  The ozone hole was monitored for the first time by the Suomi National Polar-orbiting Partnership (NPP) satellite using an instrument called the Ozone Mapping Profiler Suite (OMPS).  NOAA along with NASA have a mandate under the Clear Air Act to monitor ozone-depleting gases alone with stratospheric depletion of ozone and does so with ground and satellite measurements.  You can monitor the ozone later above Antarctica with this link!
